The present invention relates to a method for the quantitative release of natural or recombinant proteins, polypeptides (thermostable immunoligands) able to bind to the Fc-part of immunoglobulins (antibodies, in particular of the IgG class and primarily becoming bound outside the paratope) from complexes in various sample matrixes in order to make these released natural or recombinant proteins, polypeptides or peptides quantitatively available in immunochemical assays and to keep them quantitatively available. The method is characterized by mixing the sample with reagent compound that is able to bind non-specifically to immunoglobulins, and thereafter subjecting the sample to a heat treatment step followed by a cooling step.

Method for the quantitative release of natural or recombinant proteins, polypeptides or peptides

Disclosed are antibodies which can be used for the manufacture of vaccines for active and/or passive immunization of persons in need of such treatment. The invention also provides for human monoclonal antibodies that are functionally equivalent to the above-mentioned antibodies produced by any one of the cell lines CL1 through CL6 (deposited at the European Collection of Animal Cell Cultures (ECACC) at the PHLS in Porton Down, Salisbury, UK). Also provided are hybridoma and/or CHO cell lines producing any one of the antibodies disclosed and claimed herein, Also provided are mixtures of antibodies of the present invention, as well as methods of using individual antibodies or mixtures thereof for the detection, prevention and/or therapeutical treatment of HIV-1 infections in vitro and in vivo.

HIV-vaccines

Disclosed are antibodies which can be used for the manufacture of vaccines for active and/or passive immunization of persons in need of such treatment. The invention also provides for human monoclonal antibodies that are functionally equivalent to the above-mentioned antibodies produced by any one of the cell lines CL1 through CL6 (deposited at the European Collection of Animal Cell Cultures (ECACC) at the PHLS in Porton Down, Salisbury, UK). Also provided are hybridoma and/or CHO cell lines producing any one of the antibodies disclosed and claimed herein. Also provided are mixtures of antibodies of the present invention, as well as methods of using individual antibodies or mixtures thereof for the detection, prevention and/or therapeutical treatment of HIV-1 infections in vitro and in vivo.

This invention concerns peptides binding to antibodies which show neutralizing activity against different strains and clinical isolates of HIV-1 and which inhibit the fusion of cells infected with HIV-1. These peptides are combined with an adjuvant, as recombinant fusion proteins, chemically coupled to carrier molecules, as recombinant chimeric viruses or as recombinant antibodies.

Peptides that induce antibodies which neutralize genetically divergent

Novel human monoclonal anti-HIV-I antibodies and immunochemicals made from the antibodies and method of treating or preventing HIV-I infections.

Human monoclonal anti-HIV-I-antibodies

The present invention relates to fusion peptides wherein at least one peptide consisting of an amino acid sequence selected from the group consisting of SEQ ID NO: 1 through SEQ ID NO: 25 is bound to an adjuvant being a protein molecule by fusion of the respective nucleotide sequences and subsequent expression of the fusion genes in a biological expression system.

The invention is directed to human monoclonal antibodies specific for the gp41 envelope protein of human immunodeficiency virus type 1 (HIV-1). Specifically disclosed are the human monoclonal antibodies produced by the cell lines 3D6 having ECACC Accession No. 87110301, 24G3 having ECACC Accession No. 90091702 and 25C2 having ECACC Accession No. 80120601.

This invention refers to peptides binding to antibodies that show neutralizing activity against different strains and clinical isolates of HIV-1 and that inhibit the fusion of cells caused by HIV-1. These peptides are applied with an adjuvant, as recombinant fusion proteins, chemically coupled to carrier molecules, as recombinant chimeric viruses or as recombinant antibodies.
